Description

Pay-off rack for winding transformer coil

Technical Field

The utility model relates to a transformer coil coiling technical field, concretely relates to coiling is pay off rack for transformer coil.

Background

A transformer is a component utilizing the principle of electromagnetic induction, and the current transformer generally includes an iron core and a winding, wherein the winding is composed of a coil wound on the iron core. In order to facilitate production, after coil processing is finished, the coil needs to be wound first and then transported to a winding process for winding, a pay-off stand is usually adopted in the existing winding process to fix the coiled coil, and the coiled coil is mounted on a winding roller during fixing.

However, along with the increase of the power of the transformer, the size of the iron core can be increased, the number of turns of the coil can be increased, the length of the iron core which needs to be covered by the coil can be increased due to the increase of the size of the iron core, in the winding process of the coil, one end of the coil, which is close to the iron core, can move along the axial direction of the iron core, the position of the existing pay-off rack is fixed, after the end of the coil, which is close to the iron core, moves, the coil can deflect at a certain angle, and when the included angle between the coil and the part of the iron core, at which the coil is already wound, is too small, the coil can be continuously wound and displaced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a coiling is pay off rack for transformer coil to increase coil and iron core contained angle between the position of coiling coil, the accurate coiling of the coil of being convenient for.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a coiling pay off rack for transformer coil, includes the support body, installs positive and negative motor and swivelling joint on the support body and has the wind-up roll, and positive and negative motor is connected with the wind-up roll and is used for driving the wind-up roll and rotates, and the below of support body is equipped with the slide rail, support body and slide rail sliding connection.

The beneficial effect of this scheme does:

1. in this scheme, the coil of rolling is installed on the wind-up roll, and the coiling in-process, when the coil was close to the one end of iron core along the axial displacement of iron core, the coil pulling wind-up roll because the wind-up roll is installed on the support body for the support body can slide along the slide rail under the effect of pulling force, thereby avoids coil and iron core contained angle between the position of coiling coil to continue to reduce, takes place to shift when avoiding the coil to continue the coiling.

2. When the coil on the bobbin is wound on the transformer, the transformer can pull the coil, so that the bobbin rotates forwards, and the bobbin can drive the winding roller to tend to rotate forwards; the positive and negative rotating motor in the scheme is used for driving the winding roller to tend to rotate reversely, so that the bobbin can be pulled by larger acting force, the bobbin and the winding roller rotate positively, and coils between the bobbin and the transformer can be straightened, so that uniform winding is facilitated. Secondly, after the coil is stretched straight, when one end of the coil close to the transformer deflects, the frame body is pulled to slide along the sliding rail more easily, and the effect of synchronously adjusting the frame body is achieved.

The beneficial effect of this scheme does: the two slide rails can support the rack body from two sides of the rack body, and the rack body is further prevented from overturning.

Further, the frame body comprises a base and a vertical part which are distributed in an L shape, and two ends of the base are connected with the sliding rail in a sliding manner; the wind-up roll and the compression roll are both positioned on the vertical part.

The beneficial effect of this scheme does: the base in this scheme is more firm with being connected of slide rail. Secondly, the simple structure of support body in this scheme, and after the coil of rolling was installed on the wind-up roll, the focus of support body and coil still was located between two slide rails, so the support body also can not overturn.

Further, a groove with an upward opening is formed in the base and is located right below the winding roller.

The beneficial effect of this scheme does: when the diameter after the coil rolling is great, the recess in this scheme can hold the coil of installing on the wind-up roll, avoids coil and base direct contact to take place the friction with the base when avoiding the coil of rolling to rotate, thereby avoid the coil to be worn and torn.

Furthermore, a press roller is arranged on the frame body.

The beneficial effect of this scheme does: the compression roller in this scheme can be pressed on the coil, carries out tensioning and location to the coil, avoids the coil to take place to rock at the coiling in-process to make the contact position of coil and iron core distribute along the straight line, thereby make things convenient for the coiling effect of control coil more, when the coil takes place the skew or overlaps, can be more convenient adjust the coil.

Furthermore, the frame body is rotatably connected with an L-shaped frame, and the compression roller is arranged on the L-shaped frame.

The beneficial effect of this scheme does: the diameter of a coil wound on the winding roller is large, and the coil is pulled out from the lower part of the winding roller, so that the pulled coil is low, the height of the compression roller needs to be reduced to better contact with the pulled coil, and the coil is tensioned and positioned; along with the winding, the coil on the winding roller is gradually reduced, the diameter of the wound coil is gradually reduced, the height of the pulled coil is increased, the tension effect of the compression roller on the coil can be reduced only by increasing the height of the compression roller, and the phenomenon that the coil is subjected to overlarge acting force to cause plastic deformation is avoided. In this scheme, rotate L shape frame and can adjust the height of compression roller, it is convenient to adjust.

Furthermore, the L-shaped frame is connected with a handle which is in sliding fit with the L-shaped frame and is in threaded connection with the frame body.

The beneficial effect of this scheme does: through the handle can be more convenient rotate L shape frame, and need not to use other fixed knot to construct and can prevent that the handle from rotating to avoid the high change of compression roller, make the compression roller automatic stay to the tensioning and the location effect of coil.

Furthermore, a driving piece for driving the L-shaped frame to rotate is arranged on the frame body.

The beneficial effect of this scheme does: can drive L shape frame through the driving piece and rotate, and no longer need artifical adjustment, the operation is simpler.
